NICHE PARADE - Young Stepsister Blows Her Step Brother Passionately

I spotted my petite step sister washing the dishes in nothing but a tight shirt and small, revealing underwear. She has a really nice ass for a skinny girl. I was so tempted to reach out and grab it, so I did. This freaked her out. She demanded to know what I was doing there. I reminded her that I lived there, too. She told me her boyfriend was coming over soon. I asked her when, and she said in about an hour. I figured that was plenty of time to fuck around. She to be annoyed by me, but I know she's been checking me out the last few months and I told her as much. Once that was shattered, I offered to school her on how to handle a cock the right way so she could be a better girlfriend. I had her drop to her knees and whip out my meat. She immediately started sucking on it, but she wasn't doing it well enough. I grabbed her by the hair and face-fucked her good.
